Description

A method and device for data transmission

technical field

The present invention relates to the field of mobile communications, and in particular, to a method and device for data transmission.

Background technique

A radio frame of an LTE (Long Term Evolution, Long Term Evolution) system on an air interface is divided into 10 subframes with a length of 1 ms, and each subframe is composed of two slots with a length of 0.5 ms. The smallest resource granularity is called an RE (Resource Element, resource unit), which means a time-frequency lattice point composed of a time-domain symbol in the time domain and a subcarrier in the frequency domain. The uplink and downlink time-frequency domain physical resources are composed of resource blocks (Physical Resource Block, PRB). A PRB contains 12 consecutive subcarriers in the frequency domain and 7 consecutive OFDM symbols in the time domain (in the case of Extended CP, it is 6), that is, the frequency domain width is 180kHz, and the time length is 0.5ms. Two PRBs form a PRB-to-PRB-pair, which is used as a resource allocation unit for uplink data scheduling.

LTE Release 10 and later versions support carrier aggregation (CA, Carrier Aggregation). The CA system of LTE includes a primary cell (Pcell, Primary Cell) and at least one secondary cell (Scell, Secondary Cell). In order to better manage the battery consumption of UEs configured with CA, LTE provides an activation/deactivation mechanism of SCell (activation/deactivation of PCell is not supported). The activation/deactivation mechanism of the UE is based on the combination of a medium access control layer control element (MAC control element, MAC CE) and deactivation timers. The MAC CE carries the bitmap information of the SCell. When the bitmap is "1", it indicates that the corresponding SCell is activated, and when the bitmap is "0", it indicates that the corresponding SCell is deactivated. Through the bitmap information, the SCell can be activated or deactivated respectively. When the SCell is activated, the UE 1) sends an SRS (Sounding Reference Symbol, sounding reference symbol) in the SCell; 2) reports the CQI (Channel Quality Information, channel quality information)/PMI (Precoding Matrix Indication, precoding) corresponding to the SCell Matrix indication)/RI (Rank Indication, rank indication)/PTI (Precoding Type Indicator precoding type indication); 3) Detect the PDCCH (Physical Downlink Control Channel, physical downlink control channel) used for the SCell and transmission on the SCell ; 4) If the SCell is configured to send a PUCCH (Physical Uplink Control Channel, physical uplink control channel), a PUCCH signal is sent. When the SCell is deactivated, the UE in the SCell: 1) does not send SRS; 2) does not report the CQI/PMI/RI/PTI corresponding to the SCell; 3) does not transmit uplink data (including pending retransmission data); 4) RACH (Random Access Channel, random access channel) signal is not sent; 5) PDCCH used for this SCell and transmission on this SCell is not detected; 6) PUCCH signal is not sent.

In order to achieve the purpose of inter-cell interference coordination and avoidance, load balancing, and energy saving, LTE Release 12 and later versions introduce a mechanism for the base station to adaptively turn on/off cells. Turning on/off the cell corresponds to different on/off states of downlink transmission. When the cell is closed, the base station periodically sends the discovery signal according to the configuration of the discovery signal (DRS, discovery signals). Except for the DRS, the UE does not detect other signals in the deactivated SCell, and the UE performs the RRM measurement process on the SCell based on the DRS signal. When the cell is turned on, the communication between the UE and the SCell is the same as the communication in the SCell active state in Rel.10.

The goal of 5G New Radio (NR) is to meet the communication needs of mobile broadband enhancement, large-scale MTC, URLLC, etc. The key technical design of NR may adopt advanced technologies such as channel coding methods, multiple access methods, and signal waveforms that are different from LTE. According to the working scenarios designed for NR, NR systems can be deployed both below and above 6 GHz.

Considering that the frequency band below 6GHz is also the frequency band in which the LTE system is deployed. In the later stage of LTE commercial use and the early stage of NR commercial use, how to effectively allocate frequency resources below 6 GHz to meet the needs of smooth transition between LTE and NR systems is a problem to be solved. A possible way is to re-plan the use of frequency bands below 6 GHz in the commercial phase of NR, so that LTE and NR work in different frequency bands. However, in this way, the radio frequency band is hard divided into the LTE frequency band and the NR frequency band, which results in that the use of radio frequency resources cannot meet the business ratio requirements of LTE and NR, and the frequency resource use efficiency is low. Another possible way is to deploy both LTE and NR systems on the same carrier. Using this method can effectively improve the spectral efficiency, but it needs to ensure that the NR system deployed on the resources of this frequency band does not affect the normal operation of the LTE system.

Therefore, in the case of deploying LTE and NR systems on the same carrier at the same time, how to improve the efficiency of spectrum usage is a problem that needs to be solved.

At present, for the application scenario where LTE and NR are deployed on shared resources at the same time, and the shared resources correspond to one SCell of the LTE system, so that the NR system does not affect the normal operation of the LTE system, NR can be supported on the shared resources during the shutdown of the SCell in LTE. .

After the base station instructs the UE to change a certain SCell from the open state to the closed state , the UE may consider that the signaling of the OFF state of the SCell takes effect after 8 ms at the latest. Therefore, in order to support the coexistence of LTE and NR, frequent switching of SCells of LTE will result in very low spectrum usage efficiency of shared resources.

The solution of the present invention is applicable to the scenario in which the first radio access network device and the second radio access network device share resources through time division and or frequency division. For example, as shown in FIG. 2 , the first radio access network device and the second radio access network device each have exclusive resources for communicating with the served terminal device. In addition, both the first radio access network device and the second radio access network device may use the resources of the shared resources to communicate with the served terminal device.

Taking the first radio access network device as a gNB (gigabit NodeB) of the NR system, and the second radio access network device as an eNB (evolved NodeB) of the LTE system, in order to improve the ability to deploy LTE and NR systems on shared resources at the same time. The use efficiency of shared resources in the scenario, when the LTE device in this application is in the on state and in the off state, the NR system can use the shared resources, and the wireless access network device of the NR system indicates to the terminal device served by the LTE system. The resource occupancy status of the device in different states on the shared resource is convenient for the terminal device of the NR system to determine the available resources of the shared carrier, realizes the flexible and efficient coexistence of LTE and NR on the shared carrier, and improves the use of shared resources. efficiency.

Referring to FIG. 3, an embodiment of the data transmission method provided by the present invention includes:

S301: The first radio access network device determines resource configuration information, and sends the resource configuration information to a terminal device, and the terminal device receives the resource configuration information;

The resource configuration information is used to indicate information about resources occupied by the second radio access network device in the shared resources, and the resource configuration information has two status values: first resource configuration information and second resource configuration information, respectively corresponding to the first Two different states of the radio access network equipment. For example, the state of the shared resource of the second radio access network device includes an on state and an off state.

The resource configuration information is first resource configuration information or second resource configuration information, the first resource configuration information includes information on occupied resources of signals in the first signal set, and the second resource configuration information includes the first resource configuration information. Information about the resources occupied by the signals in the two signal sets, the first signal set and the second signal set both correspond to the signal sets of the second radio access network device; the first radio access network device and the second The types of radio access network devices are different, and the terminal device is a terminal device served by the second radio access network device.

Optionally, the different types of the first radio access network device and the second radio access network device mean that the first radio access network device and the second radio access network device are radio access networks that support different generations of wireless communication protocols. equipment. For example, the first radio access network device supports a 5G NR system, and the second radio access network device supports a 4G LTE system. For example, the first radio access network device is a gigabit NodeB, and the second radio access network device is an eNB.

S302: The terminal device receives the downlink information sent by the first radio access network device through the first resource in the target time unit according to the resource configuration information, or the terminal device sends the downlink information to the first radio access network device through the second resource in the target time unit according to the resource configuration information The wireless access network device sends uplink information; the first resource and the second resource are resources in the shared resources other than the occupied resources indicated by the resource configuration information; the target time unit is the first time Any one of the at least one first time unit included in the set.

S303: Downlink information sent by the first radio access network device to the terminal device through the first resource in the target time unit according to the resource configuration information, or the first radio access network device through the target time unit according to the resource configuration information The second resource receives uplink information.

The information sent or received by the first radio access network device corresponds to the terminal device. The terminal device sends uplink information, and the first radio access network device receives the uplink information sent by the terminal device. The first radio access network device sends downlink information to the terminal device, and the terminal device receives the downlink information. The manners of determining the first resource and the second resource in steps S302 and S303 are similar.

The scheduling granularity used for the communication between the first radio access network device and the served terminal device and the scheduling granularity used for the communication between the second radio access network device and the served terminal device may be different. For example, the time length of the scheduling granularity used by the first radio access network device is the length of the first time unit, and the time length of the scheduling granularity used by the second radio access network device is the length of the second time unit. For example, when the second radio access network device is an eNB of the LTE system, the length of the second time unit is 1 ms. 3GPP approved the work plan of RP-160671 on the first release of 5G New Radio (NR) standardization at the RAN#71 meeting in March 2016. The size of the scheduling resource unit in the NR system will be more flexible. The scheduling granularity of the NR system may be less than 1 ms in time. That is, the length of the first time unit will likely be smaller than the second time unit.

The embodiment of the present invention is mainly used for the first radio access network device and the terminal device served by the first radio access network device. That is, the terminal device in the embodiment of the present invention is a terminal device served by the first radio access network device.

Optionally, the uplink information includes: uplink control data and/or uplink service data. The downlink information includes downlink control data and/or downlink service data, and the downlink information does not include the discovery reference signal DRS.

For the first radio access network device, the shared resource may be a part of a frequency band of a working cell or a cell. For the second radio access network device, the shared resource may be a part of a frequency band of a working cell or a cell. As shown in FIG. 4 , the shared resource is a part of the frequency band of a working cell relative to the first radio access network device. It is a working cell relative to the second radio access network device.

On the shared resource, the first radio access network device and the second radio access network device have their own states. For example, the state of the shared resource of the first radio access network device includes an activated state and a deactivated state. The states of the shared resources of the second radio access network device include an on state and a closed state. Since the first radio access network device and the second radio access network device share resources in an orthogonal manner, the state of the second radio access network device in the shared resource state will affect the first radio access network device in the shared resource state. The resource available on the resource. Taking the second radio access network device as an eNB of the LTE system as an example, the shared resource corresponds to a cell in the LTE system, and the length of the first time unit is 1 ms. When the cell is in the ON state, the information received by the terminal equipment of the LTE system in the downlink subframe of the cell includes CRS (Cell-specific Reference Signal, cell reference signal), PSS (Primary Synchronization Signal, primary synchronization signal), SSS (Secondary Signal) Synchronization Signal, secondary synchronization signal), PBCH (Physical Broadcast Channel, physical broadcast channel), PDCCH (Physical Downlink Control Channel, physical downlink control channel), PHICH (Physical HARQ Indicator Channel, physical HARQ indicator channel), PCFICH (Physical Control Format Indicator Channel) , Physical Control Format Indicator Channel), PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel), etc. The information sent by the terminal equipment of the LTE system on the uplink subframe of the cell includes PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) , PRACH (Physical Random Access Channel, Physical Random Access Channel), SRS (Sounding Reference Symbol, Sounding Reference Symbol), PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel), etc. When the cell is in the off state, the information received by the terminal equipment of the LTE system in the downlink subframe of the cell includes CRS, PSS, SSS, etc. during the DRS burst, and the terminal equipment does not send information in the uplink subframe of the cell. In addition, when the cell is in the first special open state, the information received by the terminal equipment of the LTE system in the downlink subframe of the cell includes CRS, PSS, SSS, and PBCH, but does not include PDCCH. The terminal equipment of the LTE system is in the cell's downlink subframe. No information is sent on uplink subframes. Further, in the subsequent evolution system, the state of the shared resource corresponding to LTE may further include a second special ON state and a second OFF state. The second special open state is similar to the open state, the difference is that the state of the LTE access network device sending the shared resources to the UE served by the LTE access network device through the MAC CE is the first open state, while the LTE access network device sends the shared resource to the UE through the physical control information. The state in which the serving UE sends the shared resource is the second special enabled state. The second closed state is similar to the above closed state, the difference is that the LTE access network device sends the shared resource to the UE served by the LTE access network device through the MAC CE. The state in which the UE sends the shared resource is the second closed state. Further, the state of the LTE access network device on the shared resource may also be other states. Corresponding to the states of different LTE access network devices on the shared resources, the available resources of the first radio access network device and the terminal device served by the first radio access network device are different.

If the priority of the second radio access network device occupying the shared resources is higher than that of the first radio access network device, the terminal device served by the first radio access network device needs to obtain the state of the shared resources of the second radio access network device. The resources used by the corresponding second radio access network device on the shared resources, so as to determine which resources can be used in the shared resources when it communicates with the first radio access network device.

The terminal device served by the first radio access network device may determine the resource used by the second radio access network device on the shared resource by acquiring the resource configuration information as the first resource configuration information or the second resource configuration information. Here, the first resource configuration information corresponds to the second radio access network device in the first state of sharing resources. The second resource configuration information corresponds to the second state of the second radio access network device in the shared resource state. Optionally, the terminal device served by the first radio access network device may determine the resource used by the second radio access network device on the shared resource by acquiring the resource configuration information as one of R types of resource configuration information, where R is an integer greater than or equal to 2. The J th resource configuration information in the R types of resource configuration information includes information on occupied resources of signals in the J th resource configuration signal set. Each of the R types of resource configuration information corresponds to a signal set of the second radio access network device. Among them, J is less than or equal to R. Each of the above-mentioned R types of resource configuration information corresponds to the R types of resource sharing states of the second radio access network device respectively. Optionally, the R types of resource configuration information include the foregoing first resource configuration information and second resource configuration information. The following example is illustrated with R=2. In the case of R>2, the method and device of the present invention are similar, and the corresponding extension can be used.

For example, the first resource configuration information includes information on occupied resources of signals in the first signal set. The information on the resources occupied by the signals in the first signal set corresponds to the resources occupied by the second radio access network device when the second radio access network device is in the first state of sharing resources. On the shared resource, in a second time unit of the second radio access network device: (1) If the second time unit is a downlink second time unit, the second time unit is excluded from the second time unit. The resources other than CRS, PSS, SSS, PBCH, PDCCH, PHICH, PCFICH, and PDSCH sent by the network access device are resources available to the first radio access network device; or, in the downlink time unit, except for the second radio access network The resources other than the CRS, PSS, SSS, and PBCH sent by the network device are resources that can be used by the first radio access network device. (2) If the second time unit is an uplink second time unit, the resources in the second time unit except the PUCCH, PRACH, SRS, and PUSCH sent by the terminal equipment served by the second radio access network equipment are the first Resources available to a radio access network device.

The second resource configuration information includes information on occupied resources of signals in the second signal set. The information on the resources occupied by the signals in the second signal set corresponds to the resources occupied by the second radio access network device in the case of the second state of the shared resource by the second radio access network device. That is, on the shared resource, in a second time unit of the second radio access network device, (1) if the second time unit is a downlink time unit, the downlink time unit excludes the second radio access unit. The resources other than the DRS sent by the network access device are the resources that can be used by the first radio access network device; (2) if the second time unit is an uplink time unit, the resources in the uplink time unit are the first time unit. Resources available to a radio access network device.

The terminal device served by the first radio access network device may receive, in the target time unit, the downlink information sent by the first radio access network device on the first resource in the shared resources according to the received resource configuration information. The downlink information here includes downlink control information and/or downlink data information. Alternatively, the terminal device served by the first radio access network device may send uplink information to the first radio access network device through the second resource in the shared resources in the target time unit according to the acquired resource configuration information. The downlink information here includes uplink control information and/or uplink data information. The first resource does not include occupied resources of the signal indicated by the resource configuration information. The second resource does not include the resource occupied by the signal indicated by the resource configuration information. For example, the terminal device served by the first radio access network device may determine scheduling resources according to the received scheduling information, and determine resources that cannot be used in the scheduling resources according to the resource configuration information, thereby determining the first resource. Similarly, the second resource can be determined. In this embodiment, the state of the second radio access network device in the shared resource is different. Correspondingly, the occupied resources of the signals included in the first signal set and the second signal set are different. Both the first signal set and the second signal set correspond to the signal set of the second radio access network device. The first resource configuration information may correspond to the occupied resources of the signals of the signals in the first signal set in one second time unit, or to the occupied resources of the signals of the signals in the first signal set in multiple second time units. The second resource configuration information may correspond to the occupied resources of the signals of the signals in the second signal set in one second time unit, or to the occupied resources of the signals of the signals in the second signal set in multiple second time units. Because the first resource configuration information corresponds to the first state of the shared resource of the second radio access network device. The second resource configuration information corresponds to the second state of the shared resource of the second radio access network device. On the other hand, the state of the shared resource of the second radio access network device may be the same in multiple subframes. Therefore, the valid range of the above resource configuration information is one or more target time units. That is, the above-mentioned target time unit is any one of the at least one first time unit included in the first time set.

The first resource and the second resource are resources in the shared resources other than the occupied resources indicated by the resource configuration information, respectively. That is, the first resource does not include the resource occupied by the signal indicated by the resource configuration information, and the second resource does not include the resource occupied by the signal indicated by the resource configuration information. Because, the first resource configuration information may correspond to the occupied resources of the signals in one second time unit of the signals in the first signal set, or correspond to the occupied resources of the signals of the signals in the first signal set in multiple second time units The first resource does not include the occupied resource of the signal indicated by the resource configuration information, that is, the first resource does not include the resource located in the target time unit in the occupied resource of the signal indicated by the resource configuration information. Similarly, the second resource does not include the occupied resources of the signal indicated by the resource configuration information, that is, the second resource does not include the resource located in the target time unit among the occupied resources of the signal indicated by the resource configuration information. If the second time unit corresponds to the downlink transmission of the second radio access network device, the CRS, PSS, SSS, PBCH, PDCCH, PHICH, PCFICH, PDSCH sent by the second radio access network device are not included in the second time unit. The external resources are the resources that can be used by the first radio access network device. The terminal device served by the first radio access network device receives the downlink information sent by the first network device through the first resource. The first resource does not include the resources occupied by these information. resource. If the second time unit corresponds to the uplink transmission of the second radio access network device, the resources in the second time unit other than at least one of PUCCH, PRACH, SRS, and PUSCH configured by the second radio access network device are: The resources that can be used by the first radio access network device. The terminal device served by the first radio access network device receives downlink information sent by the first network device through the first resource, and the first resource does not include the resources occupied by the information. Similarly, if the second time unit corresponds to the downlink transmission of the second radio access network device, the second resource does not include the CRS, PSS, SSS, PBCH, PDCCH, PHICH, PCFICH, PDSCH sent by the second radio access network device. Occupied resources; if the second time unit corresponds to the uplink transmission of the second radio access network device, the second resources do not include resources configured by the second radio access network device to at least one of PUCCH, PRACH, SRS, and PUSCH. for example. The terminal device served by the first radio access network device can determine the scheduling resource according to the received scheduling information, and determine whether there are any and which resources cannot be used in the scheduling resource according to the resource configuration information, so as to determine the second resource.

The first radio access network device sends downlink information to the terminal device through the first resource in the target time unit according to the resource configuration information, and the terminal device receives the downlink information through the first radio access network device in the target time unit according to the resource configuration information. Downlink information sent by a resource. The downlink information includes downlink control information and/or downlink data information. Preferably, the downlink information here includes downlink control information, or includes downlink control information and downlink data information. Since the resources occupied by the downlink data information and the uplink data information may be indicated by the downlink control information, in this solution, the first radio access network device and the terminal device served by the first radio access network device determine the method for the resources occupied by the downlink data information and the uplink data information. It may not depend on the resource configuration information, but be completely indicated by the downlink control information. For example, the first radio access network device directly notifies, in the downlink control information, which resources need to be removed from the resources occupied by the downlink data information to the terminal device it serves. The resources occupied by the downlink control information need to be determined by the first radio access network device according to the resource configuration information. The terminal device served by the first radio access network device needs to determine the resources occupied by the downlink control information according to the resource configuration information. Optionally, the resources occupied by the downlink data information and/or the uplink control information are determined according to the indication of the downlink control information.

In this embodiment, since the first radio access network device indicates to the terminal device served by the first radio access network device the resource occupation corresponding to different states of the second access network device on the shared resource, the terminal device can determine the availability of the shared carrier accordingly. resource, and use the available resource to communicate with the first access network device. No matter what state the second access network device is in on the shared resources, the first access network device can use the shared resources, which realizes the flexible and efficient coexistence of different types of wireless access network devices on the shared resources, and improves the efficiency of the shared resources. Efficient use of shared resources. .

Taking the coexistence of LTE and NR systems as an example, the wireless access network equipment of the NR system indicates to the terminal equipment served by the LTE equipment the resource occupation corresponding to the different states of the shared resources, which is convenient for the terminal equipment of the NR system to determine the shared resources. The available resources of the carrier, the NR system can use the shared resources when the LTE device is in the on state and the off state, which realizes the flexible and efficient coexistence of LTE and NR on the shared carrier, and improves the use efficiency of the shared resources.

Optionally, referring to Figure 5, the method further includes:

S501: The terminal device determines the state of the shared resource, and the state includes an activated state and a deactivated state;

When the state of the shared resource is the active state, the terminal device receives the resource configuration information and executes the above step S302.

Similar to the scenario in which the first radio access network device and the second radio access network device share the shared resources through time division and or frequency division described in the embodiment of FIG. 3 , on the shared resources, the first radio access network device and The second radio access network devices have respective states. For example, the state of the shared resource of the first radio access network device includes an activated state and a deactivated state. If the state of the shared resource of the first radio access network device is the active state, the terminal device served by the first radio access network device receives downlink information on the shared resource, or sends uplink information. When receiving downlink information or sending uplink information on the shared resources, the terminal device needs to determine the resources occupied by the second radio access network device on the shared resources, so as to determine the resources available to itself. That is, the terminal device needs to receive the downlink information sent by the first radio access network device in the first resource in the shared resources in the target time unit according to the resource configuration information, or use the second resource in the shared resources in the target time unit according to the resource configuration information. Send uplink information to the first radio access network device. The specific method is the same as that of S302, which is not repeated here.

S502: When the state of the shared resource is in the deactivated state, the terminal device does not receive the resource configuration information; or the terminal device does not use the first resource to receive downlink information, or the terminal device does not use the first resource to receive the downlink information The second resource sends uplink information; wherein the first resource and the second resource are resources in the shared resources other than the occupied resources indicated by the resource configuration information; the downlink information includes downlink control information and/or downlink service information; the uplink information includes uplink control information and/or uplink service information.

Optionally, when the state of the shared resource is a deactivated state, the terminal device receives a discovery reference signal sent by the first radio access network device on a third resource in the shared resource. Optionally, the discovery reference signal sent by the first radio access network device on the third resource in the shared resources is used for measurement related to radio resource management (Radio Resource Management, RRM) of the terminal device, and the like.

Optionally, the terminal device needs to determine the third resource according to the resource configuration information in S301.

Optionally, referring to Figure 6, the method further includes:

S601: The first radio access network device determines the state of the shared resource, where the state includes an activated state and a deactivated state;

When the state of the shared resource is the active state, the first radio access network device determines resource configuration information and executes step S303 in the foregoing embodiment.

Similar to the description of the above embodiments, the first radio access network device and the second radio access network device on the shared resource have their own states. For the definition and determination method of shared resource status and resource configuration information, refer to the relevant descriptions of the above embodiments.

S602: When the state of the shared resource is in the deactivated state, the first radio access network device does not send the resource configuration information, or the first radio access network device does not use the first resource to send the downlink information, or the first radio access network device does not use the second resource to receive uplink information; wherein the first resource and the second resource are the shared resources other than those indicated by the resource configuration information. Occupies resources other than resources; The downlink information includes downlink control information and/or downlink service information, and the uplink information includes uplink control information and/or uplink service information.

Optionally, the method further includes: sending, by the first radio access network device, a discovery reference signal on a third resource in the shared resources. Optionally, the discovery reference signal sent by the first radio access network device on the third resource in the shared resources is used for measurement related to radio resource management (Radio Resource Management, RRM) of the terminal device, and the like. Optionally, the first radio access network device determines the third resource according to the resource configuration information; the third resource is a resource other than the occupied resource indicated by the resource configuration information in the shared resources .

In this embodiment, since the first radio access network device indicates to the terminal device served by the first radio access network device the resource occupation corresponding to different states of the second access network device on the shared resource, the terminal device can determine the availability of the shared carrier accordingly. resource, and use the available resource to communicate with the first access network device. No matter what state the second access network device is in on the shared resources, the first access network device can use the shared resources, which realizes the flexible and efficient coexistence of different types of wireless access network devices on the shared resources, and improves the efficiency of the shared resources. Efficient use of shared resources. .

The following describes the signals included in the first signal set and the second signal set in the above embodiment.

The first case of the first set of signals and the second set of signals:

Optionally, the first signal set includes a CRS (Cell-specific Reference Signal, cell-specific reference signal), and the occupied resources of the CRS in the first signal set are located in each second time unit in the first time set; the second The signal set includes CRSs, and the occupied resources of the CRSs in the second signal set are located in part of the second time units in the first time set; or, the second signal set does not include CRSs.

The first resource configuration information corresponds to the first state of the second radio access network device in the shared resource. It is assumed that the first state is the first open state of the cell. In this case, as shown in FIG. 7 , the second radio access network The information sent by the network access device includes a CRS, and the resources occupied by the CRS are located in each second time unit of the first time set. The first time set is the time when the second radio access network device is in the first state on the shared resource.

If the resource configuration information acquired by the terminal device served by the first radio access network device is the first resource configuration information, the terminal device may determine that the resources used by the second radio access network device on the shared resources include each The resources occupied by the CRS in the two time units can be determined when the device communicates with the first radio access network device, and the resources available in the shared resources do not include these resources.

The second resource configuration information corresponds to the second state of the second radio access network device in the shared resource state. Assuming that the second state is the cell-off state, in this case, the information sent by the second radio access network device includes DRS, and the occupied resources of the DRS information are located in the second time set. In the LTE system, the DRS is sent within the configured discovery signal measurement timing configuration (Discovery Signals Measurement Timing Configuration, DMTC), and the duration of the DMTC is 6 milliseconds. DRS includes PSS, SSS, and CRS, as well as a configurable Channel State Information Reference Signal (CSI-RS). The time range in which DRS is sent in DMTC is generally called a DRS burst, and the length of a DRS burst is Configurable: 1 to 5ms for FDD, 2 to 5ms for TDD. The SSS must be in the first subframe of a DRS burst; the CRS exists in every subframe in the DRS burst, and only port 0 is sent. Taking the second radio access network device being a radio access network device of the LTE system as an example, the second time set corresponds to the time of the DRS burst in the first time set. As shown in FIG. 8 , the occupied resources of the CRS in the second signal set are located in part of the second time units in the first time set. For example, the part of the second time unit is the second time unit within the time of the DRS burst included in the first time set.

The terminal device served by the first radio access network device obtains that the resource used by the second radio access network device on the shared resource is the CRS in the first time set including part of the second time unit, and can determine that it is in the first time unit. Resources available in shared resources do not include these resources.

It should be noted that the first time set may include the time of the DRS burst, or may not include the time of the DRS burst. If the time of the DRS burst is not included in the first time set, the second signal set does not include CRS. Alternatively, the first radio access network device may limit the scheduling so that the first time set does not always include the time of the DRS burst, and the second signal set does not include the CRS.

In this way, if the first indication information indicates that the resource configuration information is the first resource configuration information, the terminal device served by the first radio access network device can receive the first resource in the shared resources of the first radio access network device in the target time unit The sent downlink information, or the uplink information is sent to the first radio access network device through the second resource in the shared resources in the target time unit according to the resource configuration information. The first resource and the second resource are resources in the shared resources other than the occupied resources indicated by the resource configuration information, respectively. The first resources include resources in the shared resources other than the resources occupied by the CRS indicated by the first resource configuration information, and the second resources include resources in the shared resources other than the resources occupied by signals indicated by the first resource configuration information; If the first indication information indicates that the resource configuration information is the second resource configuration information, the terminal device served by the first radio access network device may receive, in the target time unit, the first resource sent by the first radio access network device in the shared resources. Downlink information, or send uplink information to the first radio access network device through the second resource in the shared resources in the target time unit according to the resource configuration information. The first resources include resources in the shared resources other than the resources occupied by the CRS indicated by the second resource configuration information, and the second resources include resources in the shared resources other than the resources occupied by signals indicated by the second resource configuration. .

For another example, the first resource configuration information includes the port of the CRS and the information of the frequency offset during resource mapping. The second resource configuration information corresponds to not including the CRS. If the first indication information obtained by the terminal device served by the first radio access network device indicates that the resource configuration information is the first resource configuration information, the terminal device served by the first radio access network device may determine that the first resource includes the shared resources Except for the resources occupied by the CRS of the second radio access network device in the target time unit, the second resources include resources in the shared resources except the resources occupied by the CRS of the second radio access network device in the target time unit ; If the first indication information obtained by the terminal device served by the first radio access network device indicates that the resource configuration information is the second resource configuration information, the terminal device served by the first radio access network device can determine the first resource and the second resource configuration information. The resources occupied by the CRS of the radio access network device are irrelevant, and the second resource is independent of the resources occupied by the CRS of the second radio access network device.

Optionally, in this embodiment, in addition to CRS, the first signal set further includes at least one of PSS, SSS, and PBCH; or, in addition to CRS, the first signal set also includes PSS, SSS, and PBCH , at least one of PDCCH, PHICH, and PCFICH.

In this embodiment, it is assumed that the first signal set corresponds to the first open state of the second radio access network device, and the signals sent by the second radio access network device during the first open state include CRS, PSS, SSS, PBCH, PDCCH, PHICH, PCFICH, PDSCH, etc. If the first signal set corresponds to a second on state of the second radio access network device, the signals sent by the second radio access network device during the first on state include CRS, PSS, SSS, PBCH, and the like. Wherein, the PSS and SSS in the first signal set are information sent by the second radio access network device in the shared resource in a first cycle, and the time length of the first cycle includes the time of N second time units length, N is a natural number. That is, the occupied resources of PSS and SSS in the first signal set satisfy the first period in time, the time length of the first period includes the time length of N second time units, and N is a natural number. In the LTE system, the resources occupied by the PSS sent by the radio access network device of the FDD system are located in the second time units with sequence numbers 0 and 5. In the LTE system, the resources occupied by the PSS sent by the wireless access network equipment of the TDD system are located in the second time units with sequence numbers 1 and 6, and the resources occupied by the SSS sent by the wireless access network equipment in the LTE system are located in the first time unit. The second time unit with sequence numbers 0 and 5 in the set. The resource occupied by the PBCH sent by the radio access network device in the LTE system is located in the second time unit with the sequence number 0 in the first time set. That is, the PSS and SSS in the first signal set are information sent by the second radio access network device within the shared resource with a period of five second time units.

In this embodiment, it is assumed that the second signal set corresponds to the off state of the second radio access network device, the PSS and SSS in the second signal set are sent in the shared resource in a second cycle, and the duration of the second cycle includes M The duration of the second time unit, M is a natural number greater than N. That is, the occupied resources of PSS and SSS in the first signal set satisfy the second period in time, and the time length of the first period includes the time length of M second time units, where M is greater than the above N and is a natural number. The DRS information sent by the second radio access network device is sent in a DRS burst within the configured DMTC. The DRS information includes PSS and SSS, and one DRS burst includes only one PSS/SSS. Therefore, the cycle of the DRS sent by the second radio access network device is the same as the cycle of the DMTC, which is 40ms, 80ms, or 160ms. It should be noted that the first time set may include the second time unit in which the PSS/SSS is sent in the DRS burst, or may not include the second time unit in which the PSS/SSS is sent in the DRS burst. If the first time set does not include the second time unit in which the PSS/SSS is transmitted in the burst, the second signal set does not include the PSS/SSS. Alternatively, the first radio access network device may pass scheduling restrictions such that the first time set does not always include the second time unit for transmitting PSS/SSS in the DRS burst, and the second signal set does not include PSS/SSS. If the first time set does not include the second time unit in which the PBCH is transmitted in the burst, the second signal set does not include the PBCH.

The second case of the first set of signals and the second set of signals:

Optionally, the first signal set includes at least one of PRACH, SRS, and PUCCH, and the second signal set is an empty set.

The first resource configuration information corresponds to the first state of the second radio access network device in the shared resource. Assuming that the first state is the cell-on state, the terminal device served by the second radio access network device may send PRACH on the shared resource , SRS, PUCCH and other information; the first resource configuration information corresponds to the second state of the second radio access network device in the shared resource, assuming that the second state is the cell off state, the terminal served by the second radio access network device The device does not send PRACH, SRS, PUCCH and other information on shared resources. If the resource configuration information is the first resource configuration information, the resources for communication between the terminal device served by the first radio access network device and the first radio access network device do not include the above PRACH, SRS, and PUCCH resources; if the resource configuration information is the first Second, resource configuration information, the resources of the terminal device served by the first radio access network device and the first radio access network device do not need to consider the resources of the PRACH, SRS, and PUCCH.

If the priority of the second radio access network device for occupying the shared resources is higher than that of the first radio access network device, the first radio access network device needs to avoid the resources used by the first radio access network device to send downlink information or receive uplink information in the shared resources. Resources used by networked devices. A possible way is that the communication resource itself on the shared resource of the first radio access network device has nothing to do with the resource occupied by at least one signal sent by the second radio access network device, for example, it is related to the second radio access network device. The occupied resources of sending PSS and SSS are irrelevant. In this case, the first radio access network device only needs to notify the terminal device that the resources used by the second radio access network device need to avoid the resources used by the second radio access network device for sharing resources to send downlink information or to receive uplink information. Conflicting resources of access network devices. That is, the first radio access network device only needs to notify the terminal device of resources other than PSS and SSS used by the second radio access network device.

Therefore, in addition to the CRS, the first signal set also includes at least one of PSS, SSS, and PBCH. Alternatively, the first signal set further includes at least one item of PSS, SSS, PBCH, PDCCH, PHICH, and PCFICH. If the first signal set includes PSS, the resources occupied by the PSS in the first signal set are located in the second time units with sequence numbers 0 and 5 in the first time set, which corresponds to the fact that the second radio access network device is an FDD system of the wireless access network equipment. Or, the resources occupied by the PSS in the first signal set are located in the second time units with sequence numbers 1 and 6 in the first time set, which corresponds to the second radio access network device being a radio access network device of the TDD system Case. If the first signal set includes the PSS, the resources occupied by the SSS in the first signal set are located in the second time units with sequence numbers 0 and 5 in the first time set. If the first signal set includes the PBCH, the resources occupied by the PBCH in the first signal set are located in the second time unit with the sequence number 0 in the first time set.

Further optionally, the first resource configuration information further includes configuration information of MBSFN (Multimedia Broadcastmulticast service Single Freq terminal equipment ncy Network, multicast/broadcast single frequency network), and the configuration information of the MBSFN corresponds to the configuration information of the second wireless access network device. MBSFN configuration. The second resource configuration information does not include MBSFN configuration. The LTE system supports regular subframes for transmitting unicast information to a single terminal device, and MBSFN subframes for transmitting broadcast information to multiple terminal devices. Unicast information may include: data, control information, reference signals, and/or other transmissions to specific individual terminal devices. Broadcast information may include data, control information, reference signals, and/or other transmissions sent to multiple terminal devices. Each MBSFN subframe is divided into non-MBSFN domain and MBSFN domain. The non-MBSFN domain occupies the first or the first two OFDM symbols in the MBSFN subframe, and the OFDM symbols that are not used by the MBSFN domain in the MBSFN subframe are the MBSFN domain. On the MBSFN subframe, the terminal device considers that there is no downlink scheduling data for the modified subframe, but can obtain other control information in the non-MBSFN domain of the MBSFN. In the MBSFN subframe of the second radio access network device, the second radio access network device only transmits the CRS in the non-MBSFN domain. If the terminal device served by the first radio access network device determines that the resource configuration information is the first resource configuration information, the resource for the terminal device to communicate with the first access network device depends on the MBSFN subframe configuration of the second radio access network device . For example, when the target time unit is the time within the MBSFN subframe of the second radio access network device, the resources for communication between the terminal device and the first access network device do not include the CRS in the non-MBSFN domain in the MBSFN subframe, and do not use Consider the CRS of the MBSFN domain in the MBSFN subframe.

Optionally, the resource configuration information may be obtained by receiving the first indication information sent by the first radio access network device, which is the first resource configuration information or the second resource configuration information. Optionally, the resource configuration information obtained by receiving the first indication information sent by the first radio access network device is one of R types of resource configuration information, where R is an integer greater than or equal to 2. The Jth resource configuration information in the R types of resource configuration information includes information on the resources occupied by the signals in the Jth resource configuration signal set. Each of the R types of resource configuration information corresponds to a signal set of the second radio access network device. Among them, J is less than or equal to R. Each of the above-mentioned R types of resource configuration information corresponds to the R types of resource sharing states of the second radio access network device respectively. Optionally, the R types of resource configuration information include the foregoing first resource configuration information and second resource configuration information.

The following describes the method for the first radio access network device to send resource configuration information to the terminal device in the above embodiment, and the terminal device to receive the resource configuration information:

Optionally, the first radio access network device sends first indication information to the terminal device, where the first indication information is used to indicate that the resource configuration information is the first resource configuration information or the second resource configuration information. The terminal device obtains resource configuration information by receiving the first indication information. Optionally, the first radio access network device sends first indication information to the terminal device, where the first indication information is used to indicate that the resource configuration information is one of the R types of resource configuration information. Wherein, R is an integer greater than or equal to 2. The terminal device obtains resource configuration information by receiving the first indication information.

Because the resource configuration information indicated by the first indication information corresponds to the state of the second radio access network device in the shared resource state, and the second radio access network device in the state of the shared resource is notified to the second radio access network through the MAC CE of the terminal equipment served by the network equipment. Therefore, the time from the transmission of the first indication information to the effective time of the information cannot be slower than the MACCE. Therefore, optionally, the first indication information is information included in the MAC CE sent by the first radio access network device. Optionally, the first indication information may also be physical downlink control information sent by the first radio access network device. The physical downlink control information includes physical broadcast downlink control information or physical unicast downlink control information. The terminal device served by the first access network obtains the first indication information, and can determine the resource configuration information. If the first indication information is information included in the MAC CE or physical downlink broadcast information, the resource configuration information determined by the terminal device is always valid until the terminal device receives the information for updating the resource configuration information. Optionally, the first indication information is information sent by the first radio access network device on the shared resource, or the first indication information is sent by the first radio access network device on the shared resource except for Information. Preferably, if the first indication information is physical unicast downlink control information, the first indication information is information sent by the first radio access network device on the shared resource.

Further, in the evolved version of the system of the second radio access network device, the second radio access network device may notify the terminal device served by the second radio access network device through the physical downlink control information in the state of the shared resource. of. Since the resource configuration information indicated by the first indication information corresponds to the state of the second radio access network device sharing resources, the time from the transmission of the first indication information to the effective time of the information cannot be slower than the physical downlink control information. Therefore, corresponding to the terminal equipment served by the second radio access network device notified to the second radio access network device through physical downlink control information in the state of sharing resources, the first indication information is sent by the first radio access network device physical downlink control information. The physical downlink control information includes physical broadcast downlink control information or physical unicast downlink control information. The terminal device served by the first access network obtains the first indication information, and can determine the resource configuration information. Before the terminal device receives the information for updating the resource configuration information, the resource configuration information determined by the terminal device is always valid. Optionally, the first indication information is information sent by the first radio access network device on the shared resource, or the first indication information is sent by the first radio access network device on the shared resource except for Information. Preferably, if the first indication information is physical unicast downlink control information, the first indication information is information sent by the first radio access network device on the shared resource.

Further, the method also includes:

The terminal device served by the first radio access network device receives the third indication information sent by the first radio access network device, and acquires the content of the first resource configuration information and the content of the second resource configuration information. The third indication information is information included in the RRC signaling sent by the first radio access network device. Optionally, the terminal device served by the first radio access network device receives the third indication information sent by the first radio access network device, and acquires the content of each resource configuration information in the R types of resource configuration information. The third indication information is information included in the RRC signaling sent by the first radio access network device. Optionally, the third indication information may also be MAC CE or other physical downlink control information sent by the first radio access network device. For example, the first resource configuration information includes information on occupied resources of signals in the first signal set. The first resource configuration information includes the port of the CRS and the information of the frequency offset during resource mapping. The second signal set includes the port of the CRS, the frequency offset information during resource mapping, the DMTC window, the configuration information of the DRS burst, and the like.

The following describes the method in which the terminal device determines the state of the shared resource in the above embodiment, and the first radio access network device sends the state of the shared resource to the terminal device:

The terminal device served by the first radio access network device acquires the state of the shared resource through the second indication information. The first radio access network device sends second indication information to the terminal device, where the second indication information is used to indicate the state of the shared resource. Optionally, the second indication information is information sent by the first radio access network device through a MAC CE, or information sent by the first radio access network device through a physical downlink control channel.

Optionally, the above-mentioned first indication information and second indication information are carried in the same message. The message may jointly indicate the first indication information and the second indication information. If the same piece of information is fourth indication information, the fourth indication information is shown in Table 1. It should be noted that Table 1 is only an example, and does not limit the form of the fourth indication information.

Table 1

Because the resource configuration information indicated by the first indication information corresponds to the state of the second radio access network device in the shared resource state, and the second radio access network device in the state of the shared resource is notified to the second radio access network through the MAC CE of the terminal equipment served by the network equipment. Therefore, the time from the transmission of the first indication information to the effective time of the information cannot be slower than the MACCE. Optionally, the first indication information and the second indication information are carried in the same message, for example, carried in the fourth indication information, the fourth indication information may be information sent by the first radio access network device through the MAC CE, Or it is the information sent by the first radio access network device through the physical downlink control channel.

Further, in the evolved version of the system of the second radio access network device, the second radio access network device may notify the terminal device served by the second radio access network device through the physical downlink control information in the state of the shared resource. of. Since the resource configuration information indicated by the first indication information corresponds to the state of the second radio access network device sharing resources, the time from the transmission of the first indication information to the effective time of the information cannot be slower than the physical downlink control information. Therefore, corresponding to the terminal equipment served by the second radio access network device notified to the second radio access network device through the physical downlink control information in the state of sharing resources, the fourth indication information is sent by the first radio access network device physical downlink control information.

Since the fourth indication information carries both the first indication information and the second indication information, the time from when the information carrying the fourth indication information is transmitted to when the information becomes effective cannot be slower than the time between the first indication information and the first indication information. Effective time requirements.

When the state of the first radio access network device is in the deactivated state of the shared resource, the terminal device it serves may be in a closed state for a period of time, if the first radio access network device indicates the sharing through the second indication information during this period. The state of the resource is the active state, and before the second indication information takes effect, the terminal device served by the first radio access network device needs to complete the process of opening the radio frequency link, fine synchronization with the first access network device, automatic gain adjustment, etc. . Similarly, the first radio access network device notifies the terminal device it serves to deactivate the shared carrier when the state of the shared resource is active. Before the activation signaling takes effect, the terminal device needs to complete the demodulation of the deactivation signaling, the radio frequency link shutdown and so on. On the other hand, the terminal device served by the first radio access network device obtains the resource configuration information through the first indication information. The first indication information is only related to the state of the shared resource of the second radio access network device. After the terminal device receives the first indication information and before the first indication information takes effect, it does not need to perform procedures such as opening or closing the radio frequency link, fine synchronization, and automatic gain adjustment. Therefore, the maximum value of the time elapsed between the time when the terminal device served by the first radio access network device receives the above-mentioned first indication information and when the resource configuration information indicated by the first indication information takes effect is smaller than the first threshold. Wherein, the first threshold is the maximum value of the elapsed time from when the terminal device receives the second indication information to when the state of the shared resource indicated by the second indication information takes effect. Alternatively, the terminal device served by the first radio access network device acquires the resource configuration information at the first time, and the time interval between the start point of the first time set when the resource configuration information takes effect and the first time is less than the second threshold. The second threshold is the maximum value of the elapsed time from when the second radio access network device sends the cell activation command to when the cell activation command takes effect. Optionally, the second threshold is 24ms or 34ms.
